A semicircle
What is the 2 D shape for a hemisphere?
The 2D shape of a hemisphere is a semicircle. When you take a hemisphere, which is half of a sphere, and project it onto a flat surface, it creates a semicircle, representing the curved surface. The flat side of the hemisphere corresponds to a straight line, completing the shape. Thus, the 2D representation of a hemisphere is a semicircle plus a diameter.
How many equal length sides does a semicircle have?
None A semicircle is the shape of a protractor (or half a pizza). It has one straight side and one longer curved edge.
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
Does a semicircle have a curved edge?
Yes.

What shape has one curved side and 2 straight sides?
The shape that has one curved side and two straight sides is a semicircle. A semicircle is a two-dimensional shape that is half of a circle, with one curved side and two straight sides that connect at the endpoints of the curved side. The curved side of a semicircle is a semicircular arc, while the two straight sides are diameters that intersect at the center of the circle from which the semicircle is derived.

Has one straight side and one curved side?
A shape that has one straight side and one curved side is called a semicircle. A semicircle is a two-dimensional geometric shape that consists of half of a circle. The straight side is the diameter of the circle, while the curved side is the arc that forms half of the circle's circumference.
What shape has a combination of curved and straight lines?
There are infinitely many possible answers. Two of the more common shapes are semicircle and quadrant.
Is the optical axis parallel to the curved surface?
No. It's straight through the center of the sphere that the curved surface is part of.
What is the perimeter of a semicircle with radius 8cm?
A semicircle is half a circle. So the perimeter of a semicircle is half the circumference of the whole circle plus the diameter, which is twice the radius: perimeter = 1/2 x 2{pi}r + 2r perimeter ~= 3.14x8 + 2x8 ~= 41.13cm
Is a curved surface or a straight surface better for reflection?
Neither, it depends on what you are trying to accomplish.
Would a shadow cast on Earth be straight or curved?
Well, if you had a shadow cast on earth, it would appear curved because the of the Earth's surface is curved
What is the different between a semicircle and a hemisphere?
A semicircle is a two-dimensional shape that is half of a circle, with a flat edge as the diameter. A hemisphere, on the other hand, is a three-dimensional shape that is half of a sphere, with a curved surface. Essentially, a semicircle lies in a plane, while a hemisphere is a solid object.
